THOMAS SUTOLIFFE, OF LONDON, COUNTY OF MIDDLESEX, ENGLAND.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 356,176, dated January 18, 1887.

Application filed July 13, 1886.

Serial No. 207,9}2. (No model.) Patented in England October 6, 1884. No. 13,246, and November To all whom,- it may concern.-

' Be it known that I, THOMAS SUTOLIFFE, a citizen of Great Britain, residing at London, in the county of Middlesex, England, have invented certain new and useful Improvements in Bottle Necks and Stoppers, (for which I have obtained Letters Patentin England, No. 13,246, dated October 6, 1884, and No. 13,947, dated November 16, 1885;) and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to bottle necks and stoppers; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a vertical section through the neck of the bottle provided with a stopper and constructed according to my invention. Fig. 2 is a plan view from above of the neck of the bottle with the stop 'per removed. Fig. 3 is a plan view from be low of the stopper removed from the bottle. Fig. 4 is a vertical section through a stopper constructed according to one modification of my invention. Fig. 5 is a vertical section through a stopper constructed according to another niodi-fication of my invention.

I form an oval or oblong entrance to the mouth of the bottle, jar, or other receptacle. Below this, and in the neck of the bottle, I- form upwardly-converging recesses A, constructed upon a series of curved lines pr0jecting at their ends toward the center of the bot tle-neck, and thus forming the stops 1), which prevent the stopper from being turned too far round. These recesses are opposite to each other, and have between their non-contracted ends the straight portions f, joined to them so that the surface of the interior of the neck remains smooth and unbroken.

B is an annular flange or seat formed in the neck of the bottle immediately below the said recesses A.

The stopper (shown in Figs. 1, 2, 3, 4) con sists of two parts, of which 0 is the outer part and D the inner part, which projects through the said outer part. The outer part, 0, has a conical hole, 0, through its center, and the inner part, D, is also formed conical, so as to fit into the said hole.

According to one modification of myinvention, as shown in Fig. 4, the central hole, 0, of the outer part is made straight, and the in ner part, which fits it, is also made straight, and is provided with a flange, h, at the top. This flange it bears upon the shoulder h around the hole 0, so that the inner part may not pass too far through the outer part. A recess is formed, as shown, for the reception of the flange h, so that it may not project above the top of the outer part. The lower end of the inner part, D, projects below the outer part, 0, and is provided with an annular groove or recess, 6. A thin metallic washer, g, is slipped upon the lower projecting end of the said in ner part.

E is a washer of any suitable pliable rial, such as india-rubber or cork. This washer is also slipped upon the end of the inner part into the recess 6 and holds the two parts 0 and D together. The outer part, 0, of the stopper has a flange, a, at the top of it, and is provided with bulges a on its sides immediately below the said flange. These bulges are placed opposite each other, and have straight portions 11 between them.

In placing the stopper in the bottle the bulges a pass down the straight parts f of the neck of the bottle until the washerE rests upon the flange B. The outer part of the stopper is then turned, so that the bulges a enter the recesses A in a circular direction. This causes the washer E to be pressed firmly down upon the flange B,so that the bottle is closed tightly, and the stopper is also securely held in the neck of the bottle.

The outer portion, 0, only of the stopper is turned in securing it. The inner part remains stationary, and the washer E is thus pressed down upon the flange B without any rotary motion against it. The thin metallic washer 9 allows the outer part to turn freely, and preserves the top of washer ll from being worn away by the outer part, 0, which would otherwise be rotated upon it.

I prefer to form the hole in the outer part, 0, conical, as shown at 0, so that when the mate- Int) said outer partis pressed down inside the neck of the bottle the elasticity of the washer E will allow the inner part to ease up just enough to permit the said outer part to turn freely. There is also an advantage in forming the inner part conical, as it can be pressed more equally in the molds, and can be made in larger quantities.

A simple modification of my invention is shown in Fig. In this the stopper is made in one solid piece, and is provided with the bulges a, straight portions a, and has the annular groove 6 at its lower end, into which the washers g and E are slipped, exactly as before described. This form of stopper is much cheaper than that made in two parts, and is suitable for common bottles, jars, or other receptacles.

I do not confine myself to the use ofglass bottles and stoppers, as my invention can also be applied to bottles or vessels of any mate rial, such as, earthenware jars and other receptacles.

What I claim is- 1. A bottle having an oblong or oval en trance and upwar'dly-converging recesses beneath it, the said recesses being provided with inwardly projecting stops, in combination with a stopper having upwardly-converging bulges on its sides engaging with the said recesses and an elastic washer on the lower end of the stopper for closing the bottle when the said stopper is turned in its neck.

2. A bottle having an oblong or oval entrance and upwardly-converging recessesbeneath it, the said recesses being provided with inwardly projecting stops, in combination with a stopper having bulges on its sides engaging with the said recesses, an elastic washer on the lower end of the stopper for closing the bottle when the said stopper is turned in its neck, and a thin metallic washer placed between the said elastic washer and the stopper.

3. A bottle-stopper provided with an annular groove on its end and with bulges on its sides, so that it may engage with the neck of a bottle an elastic washer for closing the bottle slipped into the groove on the end of the stopper, and a thin metallic washer placed between the elastic washer and the stopper, and held in place by the said washer.

4. A bottle-stopper consisting of a revoluble outer part provided with a central hole, a stationary inner part fitting the said central hole and being larger above than below, an

elastic washer for holding the various parts of the stopper together and closing the bottle placed on the lower end of the said inner part, and a thin metallic washer placed between the said elastic washer and the outer part of the stopper.

5. A bottle-stopper consisting of a revoluble outer part provided with a central hole and having bulges on its sides, a stationary inner part fitting the said central hole and being larger above than below, an elastic washer for holding the various parts of the stopper together and closing the bottle placed on the lower end of the said inner part, and a thin metallic washer placed between the said elastic washer and the outer part of the stopper,

in combination with a bottle having an oblong or oval entrance and upwardly-converging recesses beneath it, the said recesses being provided with inwardly-projecting stops so that the stopper may engage with and close the neck of the bottle when turned within it.

6. A bottle-stopper consisting of a revoluble outer part provided with a central conical hole, a stationary inner part having a conical portion fitting the said central hole, and an annular groove at its lower end, an elastic washer placed in the said groove, and a thin metallic washer placed between the said elastic washer and the outer part of the stopper.

7. A bottle-stopper consisting of a' revo luble outer part provided with a central coni cal hole and having'bulges on its sides, a stationary inner part having a conical portion fitting the said central hole, and an annular groove in its lower end, an elastic washer placed in the said groove, and a thin metallic washer placed between the said elastic washer and the outer part of the stopper, in combibeneath it, the said recesses being provided with inwardly-projecting stops, and an annular flange beneath the said recesses, so that the stopper may engage with the neck of the bottle when turned within it, and the elastic washer be pressed downward upon the said annular flange.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS SUTOLIFFE.
